1. A spread spectrum signal receiver adapted to receive a number of radio signals (SHF), the receiver comprising a radio signal processing unit (115) adapted to produce position/time related data (DPT) in response to the received signals (SHF), the receiver being adapted to operate the radio signal processing unit (115) on at least two processing intensity levels (OFF, STDB, TR, ACQ) each at which an amount of processing per time unit (PI) is different, characterized in thatthe radio signal processing unit (115) is at least partly implemented in a software (115s) running on a microprocessor (110), the microprocessor (110) is adapted to effect at least one separate software-controlled function (117) in addition to the at least-part implementation of the radio signal processing unit (115), such thatduring periods when the radio signal processing unit (115) operates on a relatively low processing intensity level (OFF, STDB), a first amount of processing capacity is available for the at least one separate software-controlled function (117), andduring periods when the radio processing unit (115) operates on a relatively high processing intensity level (TR, ACQ), a second amount of processing capacity is available for the at least one separate software-controlled function (117), the second amount being smaller than the first amount.
